In order to provide an insight to the prevalence of low sperm count and abnormal semen parameters in suspected subfertile/ infertile men in our environment, semen samples collected from one hundred and seventy (170) men aged 21-50 years, whose wives were seen at a private fertility clinic in Abakaliki, Nigeria with diagnosis of primary and secondary
infertility (78 and 92 respectively) were analysed in accordance with World Health Organization guidelines. Significantly high proportion (70%) of the study population had low sperm count (p < 0.05) with significantly high defective parameters (64%). Asthenozoospermia and teratozoospermia were the major abnormal parameters recorded. Higher prevalence of oligospermia was found in the civil servants and age-group 31-40 years (74% and 75% respectively). Using 105 cfu/ml as a significant level of bacteria growth, the prevalence of bacteria growth was found to be 56% of which 18% were from normospermic semen d 38% from oligospermic semen.Keywords: Abnormal semen parameters, male partners, genital infection, infertilityAfrican Journal of Reproductive Health Vol. 12 (1) 2008: pp. 67-7
